*Rate denominators were spline-interpolated population estimates/projections based on demographic data subject to ongoing revision by the state demographer (last revision as of Oct-2013). Use of onset date to count OOE-reported cases (since Jan-2013) causes changes in cases reported here from previously released reports. Numbers are provisional including confirmed, probable and suspect (since Feb-08) cases. HIV/AIDS case counts provided by Office of HIV/AIDS/STD; TB case counts provided by TB clinic. Monthly disease total reported by OOE=55(reported total=838). Due to unavailability of current birth data, congenital syphilis rates were not calculated(reported monthly cases for 2012-2014 were respectively 0,0,1; YTD totals 0,2,2).

**Reporting of novel type A influenza (reclassified as INFLU OUTBRK per CDC recommendations as of Jan-11) started in May-09.

#E. COLI O157:H7 instead of STEC was reported prior to 2006.

##Reported since Mar-07.

###S. pneumo invasive diseases (reported since Sep-05) previouly reported under separate categories grouped together as of Jan-11 per CDC recommendations.

~~Confidence intervals (not shown) for the monthly disease incidence rates provided a basis for an informal statistical test to determine if the current monthly rates changed significantly from those of the previous 5 years aggregated. Text in green where rates decreased and in red where rates increased. Statistically significant changes indicated by 'X' (rate comparisons made if 5+ cases reported in the current month of this year or previous 5 years aggregated).
